Like any other "skill", making good beer at home takes time, practice, and patience. And although one can get away with using relatively primitive equipment, it still takes hundreds, even thousands, of dollars, as well as many many many brews, to get to the point where your homebrew rivals what you can buy at the store.
I'm not sure I buy that homebrewing has become more popular due to the pandemic. Certain LHBS's may have increased sales, but...does anyone have any (current!) data that suggests a direction for the hobby? Perhaps it is indeed a regional thing. In my region (Sacramento area) it definitely appears to be on the decline.
It's a very niche hobby. And among all the other pressing concerns of our modern era, many being an actual existential crisis, I can understand why fewer people would take up the hobby.
